Peter Mandelson, the EU trade commissioner, said on Monday the US has «one-sided view» over the subsidies to Boeing after the end of a 90-day truce between the parties.

"The Americans have a very one-sided view over subsidies. They attack subsidy, as they call it, for Airbus, but give Boeing a free pass," he said.

He stressed that both Airbus and Boeing received financial support from government sources and «Boeing more so and from more sources». «In my view, this support can and should be reduced and disciplined but if that’s going to happen it should be done equally on both sides,» he said.

Mr. Mandelson said it is important to resolve the dispute without resort to the World Trade Organization. In January, the US and EU announced a 90-day truce to reach an accord in a long-lasting civil aircraft war that threatens to become the biggest dispute in the history of the WTO.

Mandelson and Robert Zoellick, the US Trade Representative, broke the negotiations in March accusing each other of slamming the phone down amid the telephone talks.

``This date doesn’t mean that it triggers any automatic action and we believe we should pause for further reflection and assess the situation,’’ European Commission spokeswoman Claude Veron-Reville said.
